How to prune hazelnut 'eta'

Late winter to early spring, before catkins fully open. Remove all basal suckers each year at ground level. In the main framework, cut one-third of the oldest canes to 40 cm above ground annually, completing full renewal over three years. Lightly tip branches in March to encourage lateral branching and improve nut set.

Annually — sucker removal plus rolling one-third renewal. Hazelnut 'Eta' follows the same management as other cobnut cultivars: annual sucker removal and gradual framework renewal. Removing oldest stems in a three-year cycle keeps the canopy productive and open for good nut development. 'Eta' is a mid-season polliniser cultivar, so maintaining a healthy open structure is important for catkin production and cross-pollination.
